@jack-austin This is the wrong forum for Raspberry Pi Pico and MicroPython. Better go to https://forum.micropython.org/

@patrickl That's indeed what I would do: just "interconnect" the UART connected to the Pi with the LTE's UART, sending data receiving from one end to the other and vice versa. Then the modem will look like it's directly connected to the Pi. Just don't call LTE and make sure you have the same speed settings everywhere. An alternative would probably to do it over BLE, but that seems like quite some more work to me.

@smoochypea You can achieve 5 minuite send intervals easily enough by sleeping for 5minuites - however long execution took. (read the time at the start and end of executing. run time is end - start sleep for 5 minuites - runtime as long as recording and sending data takes < 5 minuites you'll end up with a nicely timed 5 minuite loop) That said. without knowing more about what the rest of the datacollection code does it's rather hard to make recommendations.

Good to hear you sorted that out @theshade! If I have time I might fix Pymakr to look in that folder on a raspi, although I think there are not many people running this setup. (ps Pymakr is open source, so if you want to do that yourself with a pull request, feel free)

@archana-kadam I looke dagain at you request. What I cannot understand is, why you do not simple set the respberry Pi to 115200 baud. Besides that, you can free UART0 from the REPL and reconfigure it to any speed you like, e.g. for 9600 baud: import uos from machine import UART uos.dupterm(None) uart0 = UART(0, 9600) Be aware, that after the "uos.dupterm(None)", the REPL and print etc. is on telnet only.

@pierrot10 Hi, are you able to solve the issue?

@Nazz Will need to do the opposite of what you've done here, send from the RPi, recvieve on the FiPy (see here: https://docs.pycom.io/chapter/firmwareapi/pycom/machine/UART.html#uartreadnbytes), and then do what ever sending you require.

@seb Thank you for your reply, YES true that compute module does not have wifi or BT , so only we go with UART connection, and i have connected the fipy and RPI compute module via UART. But how shall ssh to RPI compute module and access the RPI file structure. After the serial connection now i want to send data within the RPI compute module to server. How to do this?? Thank You

@archana-kadam Normal LTE no.. unless you use a WiFi-LTE router (MiFi) or external LTE modem.

@seb I tried, but still to no avail.

@livius i did already.. still the same problem.. Now i connected my lopy to raspberry pi through usb0 and putty.. the data bieng sent by raspberry pi is showing on the terminal instead of in uart.readall()...

I'm trying to use nano-gateway with loraserver.io but I can not downstream messages just upstream. Can you share if you had the same problem?

@testos As long as you do not use SPI this does not matter. And the SPI pins can be reassigned too. And P11 (External IO 8) seems not to be connected on pytrack. Using I diode tester, I cannot detect any connection. At P10 (external IO 7) seems to be used. At least is show something like a ESD diode behavior of an active chip pin.

@hsn548 Hi I am senthamil doing my master's in telecommunication from University of south Australia. In my project progress, I am intended to send an image from raspberry pi 3 to Lopy 4 through WiFi. It would be appreciated, if you guide me to send an image from raspberry pi 3 to Lopy 4. Thanks in advance!!!! Regards senthamil

@jeromemaquoi yes, you got 'done' if on the destination side port is open and something is listen

@crumble Thanks for this insightful reply. WiFi is out of question in any form. Your other suggestions are really interesting. Could you explain the second suggestion, using UART, in a bit more detail?

@bucknall ok, thank you! I had not considered that the pytrack hasn't extra female pins, so i think i'll start with a standard usb connection, because i don't want to have to solder, at least for now. I'll have a look at the lopy-raspberry code :D

Hi @Jen, I think you might be in the wrong place! These forums are for the Pycom (https://pycom.io) products such as the WiPy, LoPy, etc. It seems as though you are using the Raspberry Pi which uses a different version of Python from that found on our devices! I'll point you towards https://www.raspberrypi.org/forums/ to find some more support for your issue! Thanks! Alex
